FRNCIS J. HEALEY .AND SIDNEY ROXVLAD SHEPPARD, OF SOUTHALL, ENGLAND.

VULCANIZING-MACHINE.

To all whom 'it may concer-n Be it known that we, FRANCIS JnnmrrAH HuaLur and SinN er RowLANo SnnrrAnD, subjects of the King of England, residing at Southall, in the county of Middlesex, England, have invented certain new and useful Improvements in Vulcanizing- Machines; and we do hereby declare the following to be a full, clear, and exact description of the inventiomsuch as will enable others skilled in the art to which it appertains to make and use the same.`

This invention relates to vulcanizing apparatus and; more particularly for use in vulcanizing continuous sheets or webs by a con tinnous process.

An ,0bject"f this invention is to provide an improved and simplified form of machine through w fiich a continuous web of material may be passed and vulcanized.

A further object of this invention is to provide a meansfor mounting a series of rollers to receive ay web of material therebetween with ad'jllsting means for some of said rollers to regula-te the bearing relation against the web passing between said rollers.

A further object of this invention is a provision for means for applying lacquer or any other material to Said web before it is passed through the treating processes.

A further object of this invention is the provision of a powdering apparatus for applying powder to the web during its treatment. i

-Further objects will be appareilt from the following specification, appended claims and drawings in which# I Figure l is a side elevation of the machine showing the arrangements of the rollers, Fig. l is a similar view thereof showing one molle for-driving said rollers and Fig. 3 is a sectional view as on the line 3 3 of Fig. l1, showing parts in elevation.

This invention enables a continuous web of rubber or similar material being vulcanized 'by-a continuous process and comprises a series of rollers which may be heated to the desired 'degree to receive the web of material therebetween, together with means for applying a lacquer or similar treatment before passing between the several rollers and means for applying powder to theweb before the completion of its treatment.

Referring to the drawings in which Similar reference numerals indicatesimilar parts there is shown a base 49 upon which the Specification ef Letters Patent. Patented Aug, 29, 191 6,

frames 50 are mounted as well as the frame 5l in which rollers 52 and 53 are journaled. The roller 53 is supported at each end by a sliding bearing 54 which may be moved by 60 the screw 55 to which the handwheel 56 is secured. The roller 52 is journaled at each end in a stationary bearing 57 and this roller cooperates with the downwardly tapering wall 5S forming a chamber 59 1n which a 65 lacquer common to the rubber trade for enameling purposes or other material may be placed. A doctor 60 supported by the lower edge of the wall 58 bears against the roller 52 and through the manipulation of thejo thumb screw Gl regulates the passage of the` liquid through the interstice between said doctor and said roller.

The frames 50 may be made uniformly and interchangeable and when assembled as 75 shown, these frames support frames 62 in which drums G3 are journaled as in the fixed bearing G4. The frames 50 support drums 65 in movable bearings upon the screws 67 to which the handwheels 68 arel secured. A 8o roller G9 is mounted in a frame 70 which may -be attached to one of the frames 50 and this;

the powder receptacle so that as Said 95 roller is rotated it continuously feeds a limited supply of powder such *as talc or French chalk to the web. This roller may be of a brush formation if so desired.

One of .the trunnions for each of the 100 drums 63 and 65 has a gear 76 secured thereto and these gears are of such proportions as to mesh with one another so that power applied to one of said gears correspondingly drives the others. the trnnnions for the drums 63 and 65 is of hollow formation to receive the pipes 77 and `78 which terminate at a'fitting 79 to which the steam supply pipe 80 and the eX- haust pipe 8l are connected. i" The pipe 77 1v10 conducts'the 'live steam to the interior of the drums and4 the pipe 7S discharges the The web The other of condensate therefrom as through the de pending elbow 82 to the exhaust pipe 81,. The escape of steam between the hollow trunnion and the pipe 78 isy checked by the packing 83 held in place by the gland 84. The several pipes 80 will be connected by flexible connections to a common source and in like manner the exhaust pipes 8l will be connected te a common exhaust outlet.

lt is arman-nt that by the use of a machine of this character, a web may be 'fed continuously' through the machine and treated on its passage therethrough. It so desired, the drum 63 and the drum 65 may each be enveloped by endless tapes shown in dotted lines, to direct the passage of the web betweenthe rollers.

Further description of this dece is thought unnecessary as it is clearly seen how the drums 63 and 65 could be heated to the desired temyierat-ure and how the several drums may be adjusted to produce the desired iwal-ingr relation upon one another and how the several drums may he driven on the desired speed. it is further understood that modificatibns may be made without departing from the spirit of the invention as the drawings are submitted for illustrative purposes only.

Having; thus described our invention, we claim 1. A machine for vulcanizingr a continuous webbingT comprising a pluralityY of driven and heated drums, some of said drums beingT supported in adjustable hearings, a rollerin advance. of said drums to apply a lacquer to said webbing preparatory -to its passage between the heated drums and means whereby the thickness of Vthe film of lacquer may be regulated.

2. A machine for vulcanizinga contin nous webbing, comprising a plurality of driven and heated drums to reoeiveacorr tinuous webbing therebetween, a. roller for applying a. film of lacquer to said webbingr preparatory to its passage between said ineens-a drums, and a powdering device disposed bel-.wenn some of said rollers for applying i a powder to said webbing in its treatment between said drums. i

3. A machine for" vulcanizing a continuous weiibing comprising a frame, a plurality of drums journaled in fixed bearings, a plurality of corresponding drums journaled in movable hearings, each of said drums being disposed to 'establish an pinning action on the two adjacent drums in the opposite row of drums, said drums being relatively adjustable to vary. the thickness of an inserted' web therebetween, a roller for applyingY lacquer to a web before passing through said drums and -a powderingv device for applying powder to an inserted web during the treatment of the web in said drums.

4. A machine for vulcanizing a continuous webbing comprising a frame, a plurality ot driven and heated rollers journaled in said frame in fixed bearings, a. pluralit);Y of driven and heated drums journaled in said frame in moi-'able bearings, said second mentioned drums being in staggered relation to said first mentioned drums` said frames beingT disposed to have their, perip'heries contact with and bind against a webbing passingr between said drums, a lacquering roller carried bv said frame in advance of said heated drums, means for Varyingr the thickness of a film of lacquer applied to a web passing under said rollerand a pou-dering device carried by said frame between some of said heated drums disposed to' supply a powder to a web-passing between said heated drums in the treatment ot said web.

ln testimony whereof we affix our siena- `turcs in presence of two witnesses.
